WATER-METER.

SPECIFICATION forming part of Letters Patent No. 447,595, dated March 3, 1891.

Application filed March '7, 1890- To all whom it may concern.-

of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in ater-Meters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the draw in gs accompanying this specification.

In my invention the water is admit-ted to a chamber in which is located a swinging valve, which is forced openby the pressure of the water behind it when the faucet is opened. With the valve is connected lever-work that operr 5 ates a slide located under the discharge-orifice of a hopper that contains fine emery or some equivalent granular material. The emery falls through the opening into a graduated tube or receptacle below, and the accretion or gathering of the emery in the tube indicates the amount of water that flows through the meter. The slide under the orifice of the hopper moves in and out under different pressures on the-valve, allowing the flow of more or less of the emery, thus indicating corresponding amounts. The invention consists in the combinations embodied in the claim at the end of this specification.

In the drawings, Figure 1 is a view, partially in elevation and partially in section, of the apparatus. Fig. 2 is a plan view of the meter-chamber, showing also a portion of the weighted lever which is attached to the valve. Figs. 3 and at are cross-sections, respectively, in lines 0: 0c and g yof Fig. 1.- Fig. 5 is a diagram showing a plan view of the pinion and lever Work by which the graduating slide is operated.

A indicates the receiving-chamber, B and 40 O the induction and eduction pipes connected therewith, and D a cook or faucet in the ed uction-pipe, by which the water is drawn off.

E is a swinging valve located in the receivlug-chamber and standing crosswise of the same and resting vertically against an abutment a when the water is shut off. \Vhen the cock or faucet is opened to allow the flow of water, the pressure behind the valve opens it and allows the water to run freely through the chamber. The degree of its opening Serial No. 343,064:- (No model.)

movement depends upon the degree to which the faucet is opened.

G is a hopper located above the meter and containing a body of fine emery or other granular material that slowly runs through an orifice Z) in the bottom of the hopper, like sand in an hour-glass.

H is a long tube or receptacle below the hopper, which catches and contains the emery as it falls from. the hopper, a tube or neck I connecting the two parts. This tube or recept-acle H has a transparent face 0, on which is marked a scale cl, running from a lower to a higher denomination and designed to indicate the amount of water which runs through the meter by the gathering and rise of the emery within the tube opposite the graduations.

. K is a lever outside the receiving-chamber A, attached to the axis-of the valve E and moving up and down as the valve is swung out and in. A sliding weight L may be attached to the lever to weight the valve to any desired pressure.

M is a slide that rests under the dischargeorifice b of the emery-hopper, and is movable out and into open more or less of the dis charge-opening, and thus grade the flow of emery through the same. The discharge-orifice b may be made of any desired form, or more than one orifice may be used. The drawings show it of V shape, so that as the slide moves out it uncovers constantly-increasing areas of opening.

J indicates a small pinion, with which engage two rods P and R, having racks f f at their ends that gear with the pinion. The rod P forms a continuation of the slide M, while the rod R extends down verticallyand is pivoted at g to the valve-lever K. here 0 the movements of the valve are considerable under heavy pressures and the flow is rapid through the faucet, it may be necessary to locate the pivot g near the inner end of the lever, where the vertical movement will be small.

It will be seen that when the faucet is opened and the valve is opened by the pressure behind it the lever K will be raised and with it the connecting-rod R, thus giving rotoo tary motion to the pinion J. Consequently the slide M will be correspondingly drawn out by reason of the engagement of rod P with the pinion. The greater the throw of the valve under more rapid running of the water the greater will be the movement of the slide and the greater will be the escape of the emery into the graduated receptacle below.

It will be noticed in this invention that the movements of the slide M out and in will be regular and unvarying in degree, and that therefore the flow of the sand from the hopper will be uniform.

Having described my invention, I do not simply and broadly claim a proportional water-meter, nor do I claim a device operated by the openingof the valve in the receiving-ehaim her to regulate the escape of the registering medium; but I claim In a water-meter, the combination of the my name in the presence of two subscribing 30 witnesses.
